Abstract
The invention discloses a concrete pipe pile which comprises a pipe wall formed by an inner surface and an outer surface in surrounding manner. Reinforcement members are disposed in the pipe wall. The concrete pipe pile is characterized in that spiral projections are coaxially arranged around the outer surface. The concrete pipe pile has the advantages that the concrete pipe pile is convenient to construct, the friction of the concrete pipe pile with soil mass is increased, and bearing capacity and stability of the concrete pipe pile are improved.
Description
Technical field
The present invention relates to a kind of building pile tube, especially relate to a kind of concrete tubular pile.
Background technology
Concrete tubular pile is adopted in foundation engineering widely.The profile of traditional concrete pile tube is generally linear pattern, the shortcoming of this pile tube be and the soil body between frictional force less, when needs satisfy bigger bearing capacity, often need increase the length or the quantity of pile tube, this can increase the cost of whole pile foundation engineering.In order to increase the frictional force between the pile tube and the soil body, improve the supporting capacity of pile tube, people have done the improvement of many aspects to concrete tubular pile; Chinese invention patent Shen Qing Publication manual as on March 11st, 2009, disclosed publication number was CN 101381992A discloses a kind of prestressed concrete pipe pile, is cylinder, and the centre is hollow; Comprise tube wall; In the outer circumference surface design gear shape structure of tube wall, with the surface area of raising pile tube, and then the supporting capacity of raising pile tube.Though this design can improve the contact area between the pile tube and the soil body to a certain extent, increase frictional force, shortcoming is when piling construction, need apply bigger vertical forces to pile tube, and is high to the piling equipment requirements, also increased the piling difficulty simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides the concrete tubular pile that the frictional force between a kind of that be convenient to construct and soil body increases.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of concrete tubular pile, comprise the tube wall that surrounds by inner surface and external surface, and be provided with steel reinforcing spare in the described tube wall, be coaxially arranged with helical raised around described external surface.
Preferably, the helical angle of described helical raised is 30 ° ~ 87 °.
Preferably, described helical raised is continuous helical raised.
Preferably, described helical raised is discontinuous helical raised.
Preferably, evenly have a plurality of grooves on the described helical raised, described groove is divided into several segments at interval with described helical raised along the spiral trend.
Preferably, observe from cross section, protruding the above the quantity of groove of each circle of described helical raised is six ~ 40.
Compared with prior art; The invention has the advantages that: the external surface of concrete tubular pile of the present invention is coaxially arranged with helical raised; When piling applies vertical forces to pile tube, impose torsion, the helical raised of formation helps carrying out smoothly of the process of driving piles; The design of helical raised increases the surface area of pile tube, and the increase of the contact area between the soil body, so the frictional force between the pile tube and the soil body increases the supporting capacity of pile tube and stable the raising; When on helical raised, evenly having a plurality of groove; These grooves are divided into several segments at interval with helical raised; This moment, thereby this discontinuous helical raised further increased between the pile tube and the soil body in the frictional force at further increase pile tube surface area; Reduce the pile tube materials, alleviate the pile tube deadweight.
